  4. Switching to a fixed-rate loan — Restarting your mortgage loan gives you options to reverse your adjustable-rate mortgage to a fixed rate ensures that your interest rate does not fluctuate and remains constant throughout the term.

Why Restarting your 30-Year Mortgage is a Bad Idea

On the flip side, restarting your 30-year mortgage has its better share of disadvantages. Refinancing your 30-year mortgage commences the amortization process, which may lengthen the payment period. For instance, if you have paid your mortgage for seven years and then opt to refinance with a new 30-year mortgage, you end up making monthly payments for 37 years.

However, for some individuals, this plan sounds good. For example, if you have been paying your loan for 10 or 20 years, then the lifetime interest may not make financial sense in the long term considering the extra costs involved. Overall, the majority of homeowners refinance to shortened terms that do not lengthen the mortgage payment period such as a 15 or 20-year mortgage and often provide low-interest rates as opposed to a 30-year mortgage.

Other Options for Restarting your 30 Years Mortgage


Instead of a shortened loan term with higher monthly payments, some homeowners prefer to prepay their mortgage. This mean, the homeowners commit some extra cash that will affect the principal amount. For example, instead of paying $743/month, you pay $750 whereby the excess goes to the principal. Often, people determine how much to pay by rounding the numbers by tens or hundreds.

Refinance and Prepay

Also known as refinance-to-prepay, homeowners use this method to refinance their mortgage to a lower rate of interest without altering the loan term and then prepay the
new loan via total monthly savings. Refinancing helps reduce the monthly principal and interest payment, which results in savings that you send to the lender alongside the monthly payment. Therefore, over time, the excess savings you will be paying for the mortgage will continue decreasing the overall amount owed.
